To (/.f/v/v 1/'71 ont if /m/l/ (fon/c0771,.-

Be it known that I, Pn'rnu E. (loop, a citizen of the United States, residingl at .Etna (ii-ecn, i

in the county of liosciusko and State of ,Indiana, have invented certain new and useful lmprovements in Spreaders Yfor 'el`hreshing-nlachines` of which the following' is a specification.

The object of my present invention is to provide means in a thresliing-machine or separater to spread the incoming' material from a narrow cylinder evenly over rake-bars of considerably greater width.

The accompanying' drawings illustrate my invention.

Figure 1 a vertical sectional view of a machine embodying' my invention on the line 1 1 of Fig'. 2. Fig'. 2 is a plan with the top of the separator removed; Fig. 3, a section on line 3 3 of Fig'. 1; Fig'. e, a partial plan, on an enlarged scale, of the parts shown in Fig. 2; Fig. a section, on an enlarged scale, on line 5 of Fig. l; and Fig'. 6, an enlarged detail of the adjacent ends of the two sets of rake-bars.

In the drawings, indicates a separator of any desired form provided with the usual separating-cylinder and concave 11. rlhis cylinderand concave is, as usual, of less width than the machine proper and discharges upon a pair of rake-bar structures 12 12, which are of considerably greater width than the cylinder and concave and lead upward and backward therefrom. The rake-bar struetures 12 12 are supported at their lforward ends by upwardly-inclined links 13 and at their rear ends are carried by standards 11, which are carried by the cranks ot' a usual crank-shaft 15. 3tunning' backward from the rear ends of the rakebar structures 12 12 are corresponding' rake-bar structures 16 16, the forward ends of which are attached each to one of the standards 11 and at their rear ends are carried by upwardly-inclined links 1T.

For the purpose of spreading the Inaterial evenly o'ver the rake-bar structures 1212 I mount above the forward ends of said rakebars, immediately to the rear of the cylinder and parallel therewith, a crank-shaft 20, provided with a pair of cranked portions 21. Journaled upon each crank-shaft 21 is a block 22, in which is journaled one end of a lingershaft 23, said shaft extending' at right ang'les to the shaft 2O rearward and upward over one of the rake-bar structures 12. The rear end of each linger-shaft 23 is journaled in a l j l block 2l, which is pivotally attached to the lower end of a swinging' link 25, which link is suspended from the casing' 1t). The pivotal axis of each link 25 and the block 21, attached thereto, are at right angles to the linger-shaft 23 and parallel with the crank-shaft 20. Secured to each linger-shaft is an uliwardly-extending' arm 2G, to the upper end of which is swiveled a block 2T on an axis at right angles to the axis of the linger-shaft. Hinged to the block 2T, at right angles thereto and also at rig'ht angles to the linger-shaft 23 on an axis parallel to said shaft 23, is a link 28. This link extends transversely outward toward the adjacent side of the casing' 10 and is pivoted upon a substantially horizontal axis to the upper end of a pin 29, the shank of which is substantially vertical and journaled in suitable bearing-blocks 30, attached to the casing' 1l). Each linger-shaft 23 carries a plurality of lingers 23@ which extend downwardly toward the rake-bar structure 12.

The shaft 2O is driven in the direction indicated by the arrows in Figs. 1 and 1 by any suitable means, so that the linger-shafts 23 will have their forward ends revolved about the axis of the shaft 2l), while the rear ends swingen thelinks 25. At the same time,owing' to the arm 2li, block 27, link 28, and pin 29, each shaft 23 will be also oscillated about its own axis, so that the lingers 23 will be lirst swungl toward the center of the machine, as shown at the upper left-hand corner of Fig'. 2,- then moved downward toward the adjacent rake-bar structure, and thence rearward and outward to the position shown in Fig'. 4 and in the lower left-hand corner of Fig'. 2, thus spreading' the straw Vfrom the center rearward and outward, lirst toward one side and then toward the other.

l claim as my invention- 1. ln a separator, the combination, with threshing' means and receiving means arranged to the rear thereof, of spreading' means arranged above said rceeiving means, said spreading means consisting' of a crank-shaft, a finger-shaft extending rearward over thereceiving' means, a bearing-block journaled on the crank `and forming a journal for the linger-shaft, a jouri'ialing supporting' means for the opposite end of the linger-shaft, an arm carried by the linger-shaft, and a link pivoted at one end to the linger-shaft and at the other end to a stationary support.

2. ln a separator, the combination, with th resh i ng' means and receiving' means arranged IOO to the rear thereof, of spreading means arranged over said receiving means4 and consisting of a crank-shaft, a finger-shaft, a block journaled on the crank of the crank-shaft and forming a journal-hearing for the fingershaft, a link pivotecl to -a stationary support, a block pivoted to said link and Jforming a journal-hearing for the other end ofv the iinger-shat, an arm carried by the finger-shaft, and a link swiveled to said arm at one end and swivelecl to a support at the other end, substantially as and for the purpose set forth.

3. A spreader Jfor separators consisting of, a crank-shaft, a finger-shaft extending rearward over the receiving means, a hearinglolook journaled on the crank and forming a journal for the iinger-shaft, a journaling snpporting means for the opposite end of the finger-shaft, an arm `Carried by the ingershaft, and a link pivoted at one end to the fingershaft and at the other end to a stationary support.

4. A spreader for separators consisting of, a eran-shaft, a finger-shaft, a block journaled on -the crank of the crank-shaft and Jforming a journal -hearing for ,the fingershaft, a link pivoted to a stationary support, a block pivoted to said link and forming a journal-hearing for the other end of the iinger-shaft, an arm earried'by the nger-shaft, and a link swiveled to said arm at one end and swiveled to a support at the other end, as and for the purpose set forth.

In witness whereof I have hereunto set my hand and seal, at Etna Green, Indiana, this 31st day of December, A. D. 1904.
